improvements relate to fleshing and slating machines of well knowii-types, where in a skin is carried by' an eridless'rubber barid into close contact with a roll having knifeblades of steel or slate set "ari'g'ularly or spirally upon its surface".- Iii such machines as heretofore constructed two" workmen are required, one feeding the skins to the roll and another standing at the opposite end of the machine removing the skins as they are delivered by the roll. These machines are dan gerous to one or the other of these workmen, according to the direction in which the roll rotates. In the older form of machine the lower side of the roll moves in the direction of the upper side of the endless band, making the machine very hazardous to the workman who feeds the skins to the machine. In the newer form of machine the roll rotates in the opposite direction, making the machine hazardous to the workman who receives the skins.

My invention is especially applicable to said newer form of machine, and consists in the addition thereto of a stripping device by means of which the removal of the skin from the machine upon its delivery by the roll is automatically efiected, so that it is nolonger necessary for a workman to remove the skins from the roll. Further, the stripping device acts as an obstacle, preventing any one from accidentally placing his hand near the inwardly-rotating lower side of the roll.

In the accompanying drawings, Figure I is a vertical central section of a machine having one embodiment of my invention applied to it. Fig. II is a similar partial section of a machine having another embodiment of my invention applied to it.

Referring to the form of machine disclosed in Fig. I, the parallel rollers 2 2, which carry the endless rubber band 3, are suitably j ournaled upon the table 1. Above the upper side of the band 3 and with its periphery nearly or quite in contact therewith is mounted the mainroll 1 4, which may befa fleshing'or slating roll ofany construction. As is'well -known',}it is customary in these'mai-x chines to provide rolls of differing construe tion "and function according to the character of the slr'i'nsto bejliandled, and my improve ments areapplicable-to machines of this typedrrespective"of" the nature or the rolls I which may be used fo'r' treatingthe skins.

Immediately in the rear of the r'oll 1 4' there is mounted a grip-rdllfiwhich consists'iofi'a' grooved metallic" roller mounted with its lower surface below" the normal: 4 level of the upper" section 'of' the endless: band; against which it presses with corresponding 'tension. It is situated near to the roll 4 in order to lessen the space between the points where the two rollers touch the band. Immediately beneath the roller 4 a pressure-roller 6 is mounted on vertically-sliding journal-boxes held up by twin slide-rods, of which one is shown at 7, operated by a treadle 8. The pulleys and gears, by which the rolls are driven, are not shown in the drawings, their arrangement being well-known; but the direction in which the rolls rotate is indicated by arrows.

Thus r'ar I have described only the parts of the machine as it has been ordinarily constructed prior to my invention. Its operation is well understood. The grip-roll 5 has its periphery rotating in the same direction as the part of the endless band which it touches, and accordingly the skin between the two is drawn with the band, notwithstanding the rotation of the roll 4 in the opposite direction. The pressure-roller 6 when lowered permits the skin to be advanced far enough to be caught by the grip-roll, and when this has been accomplished the pressureroller is raised so as to increase the'efliciency of the action of the roll 4. In such a machine a Workman usually stands in the rear in order to strip the skins, which tend to adhere to the grip-roll and must be removed therefrom manually. This operation is hazardous, because the grip-roll and the main roll 4 are necessarily near together. Their opposing surfaces rotate inwardly, and if the hand of the workman who is removing the skin from the grip-roll remains too long upon the roll there is danger of serious accident. My invention overcomes this danger and lessens or does away with the necessity for the second workman in the rear of the machine. I mount a roller 10, having its surface provided with bristles or wire brushes in pro):- imity to the grip-roll It is driven'by the pinion 11, meshing with the pinion 12, which engages a gear upon the end of the grip-roll, the direction of rotation being indicated by the arrow in Fig. I. By this roller 10 the skins are stripped from the grip-roll, so that they fall upon the endless band and are by it delivered over the edge of the machine without the necessity of manual intervention.

In Fig. II, I have shown an alternative form of my invention, in which in place of the brushing-roller 10 there is an endless band 15, mounted between rolls 16 and 17, of which the lower roll 16 is driven by a pinion 18, which meshes with a pinion 19, which in turn meshes with a gear upon the end of the grip-roll, thus effecting rotation of the endless band in contact with the grip-roll, and etfectually stripping the skins from it.

It will be understood that my invention is not thus limited to the two specific means which I have disclosed, as other forms of rolls or devices by which the skins are stripped from the grip-roll may be employed. It is, however, important that the stripping device, whatever its nature, be so placed as to afi'ord an effective barrier to prevent any one standing in the rear of the machine from accidentally placing his hand in proximity to the point where the main roll 4 and the grip-roll 6 are turning inwardly together.

Having thus described my invention, I

claim I In a machine of the character described, the combination of the main roll; the griproll; an endless band in contact with both; and a stripping device for stripping the skins from the grip-roll, interposed in position to afford a barrier which prevents the hand of the workman from being placed in proximity to the point where the adjacent surfaces of the main roll and the grip-roll turn in together.

In testimony whereof I have hereunto signed my name, at Philadelphia, Pennsyl- Vania, this 23d day of March, 1905.
